Continuous furnace, the heated products are transported with the help of walking (moving) beam. When moving the beams up the product lying on the stationary hearth furnace is raised and transferred along with them on a certain distance (pitch) of the subsequent horizontal movement (along the furnace). Then the beams are lowered, and the product is again placed on a stationary. At the end of the cycle the movable beam located slightly below the level of a stationary hearth returns to its original position. By repeating these cycles the products are transferred through the furnace heated up to 950…1250°С.
Walking beam furnace is used for heat treatment and steel billets and products heating in the steel and engineering industries. The furnace are heated by gas or liquid fuel.
